From Melvin Nicholson Photography, a stunning picture of a natural phenomenon that's only slightly cooler than its name:
Unbelievable fog bow (otherwise known as a white rainbow) down on Rannoch Moor near Glencoe in Scotland on Sunday. I was so lucky to be shooting this wonderful isolated tree at the time as the Fog Bow framed it beautifully.
